Error using * in a simple matlab program

>> format short e
C=1;
O=0;
y=3;
m=1;
w=50;
t=0:1:10;
f=C.*exp(-(y.*t)/(2.*m))*cos(w.*t+O);
disp([t,f])

Error using  * 
Inner matrix dimensions must agree.

[Maxim Gaida]

y=log(abs(x))*(x*cos(x)+log(abs(x)))

Error using *

Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*

[Birdman]

C=1; 
O=0; 
y=3; 
m=1; 
w=50;
t=0:1:10; 
f=C.*exp(-(y.*t)./(2.*m)).*cos(w.*t+O);

Be careful that you should be doing element-wise multiplication while multipyling the exp term with cos term.

thank you! its worked now!

Can u show is the example of this equation because I'm having the same error.
